______________________ – A group of cells that perform a single
function is called a tissue.
There are 4 basic types of tissue:
1.____________________ – glands and tissues that cover interior
and exterior body surfaces (ex: skin)
2.____________________ – provides support for the body and
connects its parts (ex: bone, cartilage)
3.____________________ – transmits nerve impulses (ex: nerve
cells, brain cells)
4.____________________ – enables the body to move (ex: heart,
bicep)

The eleven organ systems of the human body work together to maintai
homeostasis in the body as a whole.
Homeostasis is the ability to keep an internal balance despite changes in
external conditions.
Examples:
•When your body temperature gets too high, you sweat.
•When your body temperature gets too low, you shiver.
•When your diaphragm (your breathing muscle) gets irritated, you
hiccup.
The_hypothalmus is the area of the brain that controls homeostasis.
In order to maintain homeostasis, your body relies on a
feed back system_.
Negative Feedback – The body produces a response that is the
opposite of the stimulus. This keeps the body in balance.
Ex – cold temperatures produce a shivering effect to keep warm
Positive Feed back – the body overproduces a response to a stimulus
in order to prevent shock or damage.
Ex – The body produces an unusual amount of adrenaline
when scared in order to enhance “fight or flight” mode
The 4 ways we will study body systems is to
categorize them into the following functions:
1. Regulation: Excretory & Nervous Systems
2. Nutrient absorption: Respiration, digestion and
circulatory systems
3. Defense: Immune, Integumentary, Lymphatic,
Skeletal, & Muscular systems
4. Reproduction: Reproductive & Endocrine systems
Muscular System
Provides movement
Skeletal System
Supports the body and protects
organs
Circulatory System
Transports nutrients and gases
Nervous System
Transmits messages through the body
Lymphatic (Immune) System
Protects the body against infection
Respiratory System
Facilitates gas exchange with the
environment
Endocrine System
Produces hormones and is
responsible for growth and
development
Thyroid gland
Digestive System
Breaks down food into chemical
energy that the body can use
Excretory System
Removes toxins from the body
Reproductive System
Produces offspring
Integumentary system
Skin – protects the body
